AC Freezer Pro 7

Just when I have received my PSU yesterday, a postman honked at my gate this morning. My AC Freezer Pro 7 is finally here after 19 days of delivery, all the way from Performance-PCs.com.

Packaging.

Well protected.

Looks good.

Inside the box...

Compare with stock Intel unit.

Ready for action.

Since there are already a lot of product reviews available in the Internet, I'll not going into product detail. Anyway, I believe my home office is one of the most "computer-unfriendly" environments out there - high ambient temperature all day long. So how well does this unit perform? Let's see...

My rig stays in Coolermaster Centurion 531 case, with 120mm fan for both intake and exhaust. Intake fan speed at around 1260RPM, exhaust spins at around 1740RPM, and CPU fan at 2700RPM. Room temp at around 30c. With closed panel, CPU temperature reads at 47c, System temperature rises from 39c to 41c, PWM1 temp hits 48c from 40c, and PWM3 temp hits 45c from 39c.

I believe it's due the direction which the AC Freezer fan is blowing. Compare with Intel stock unit, Intel's unit is blowing down to the motherboard and thus able to bring down the surrounding temperature more effective, while AC Freezer fan is blowing straight to the exhaust side of the case with only little flow to the motherboard.

So my conclusion, not satisfactory at the moment but since have to wait for the thermal paste to run in, so I expect a slightly lower temp reading by then. Perhaps other people carried out the tests under a more cooler environment, and thus able to have lower temp reading. Maybe I should get an air-conditioning unit for my room.
